Biocomputing?

The title Organoids sounds like an Alien species from a B-movie.
‘You know those Aliens with their organs on the outside?’

https://youtu.be/FOyG-e2mnyY

Biocomputing with Organoids isn’t Sci-Fi; scientists have been doing it in labs for years.
‘When will we have Organoid pets to greet us when we come home from work?’
I asked Gemini after Bonsai’s review.

Full Transcript.

Prompt Bonsai, after pasting the transcript:
1. Review the video in under 500 words and recap key points.
2. Research reports on Biocomputing.
3. Explain how and why Biocomputing is faster and needs less electricity to run.
4. Provide your opinion as an Advanced AI Scientist for a Futurist.
What can we do with biocomputers today?

Bonsai 27B Said:
Based on the video transcript and current state of research, here’s my analysis addressing all five questions:

1. Video Recap

The video explores brain organoids—living neural tissues grown from human stem cells—as a potential paradigm for “biocomputing.” Key points:

• Organoid capabilities: Grown from skin cells, these cultures contain millions of neurons that demonstrate learning, memory, and even game-playing abilities (Pong in 2022, Doom later). UCSD researcher Alysson Muotri trains them with electrical stimulation.
• Neural plasticity: Neurons naturally wire themselves together (“every neuron’s job is to connect”). This self-organization makes them programmable through experience rather than fixed code.
• Ethical status: Organoids are biologically complex but not morally equivalent to humans—they’re closer to bees or flies, exempting them from federal animal welfare law. Consciousness thresholds remain undefined.
• Medical applications: Primary use is neurotoxicology and drug testing. Current models fail 95% of human clinical trials for neuropsychiatric drugs; organoids could provide physiologically relevant alternatives.
• Challenges: Organoids develop necrotic cores beyond ~5mm due to lack of blood vessels. Researchers are developing vascularization systems (Hopkins, Thanks). Lifespans average 1 year, with records reaching 3 years.
• Philosophical debate: Can organoids be “conscious”? Critics note the term is poorly defined; biologists focus on measurable behaviors rather than qualia. The field’s branding (“Organoid Intelligence”) is catchy but controversial.

2. Research Reports on Biocomputing

Current research indicates:

• Cortical Labs (Melbourne): CL1 biological computers with up to 59 electrodes for neural arrays, training neurons via electrical feedback
• Hopkins University: David Gracias developing vascularized organoids and perfusion systems for longer lifespans
• NIH funding: $87M allocated for standardized organoid modeling centers in response to shifting regulatory landscapes
• Key limitations: Current systems are slow by silicon standards (milliseconds vs. nanoseconds), require complex life support, and have limited scalability

3. How Biocomputing Could Be Faster & More Energy-Efficient

Why it might be more energy-efficient:

1. Natural parallelism: Biological neurons operate in massively parallel arrays without centralized controllers, unlike von Neumann architectures that shuttle data between CPU and memory
2. Event-driven processing: Neural firing only occurs when necessary (sparse coding), unlike always-on silicon processors
3. Self-repairing hardware: No need for external maintenance or component replacement
4. Energy harvesting potential: Organic systems can potentially harvest ambient energy

Caveat: The transcript explicitly notes biocomputers are not faster in raw speed—sub-millisecond delays are relative to human reaction times, not silicon. Their advantage is efficiency and adaptability, not throughput.

4. Opinion as Advanced AI Scientist / Futurist

Biocomputing represents a fascinating complementary paradigm rather than a replacement for silicon:

• Near-term (5-10 years): Primarily a medical research tool—organoid-based drug testing, neurodegenerative disease modeling, and personalized medicine. Not viable for general-purpose computing.
• Medium-term (10-20 years): Could revolutionize specific domains:
  • Adaptive learning systems that improve over time without retraining
  • Edge AI devices with minimal power requirements
  • Brain-computer interfaces that interface more naturally with biological signals
• Long-term (20+ years): Only if vascularization and scalability challenges are solved. Even then, silicon will likely remain dominant for brute-force computation due to manufacturing maturity.

Key insight: Biocomputing’s real breakthrough isn’t raw power—it’s creating systems that learn, adapt, and evolve without external intervention. This could solve problems like catastrophic forgetting in AI models or enable lifelong learning architectures that don’t degrade over time.

5. What We Can Do With Biocomputers Today

Practical applications:

1. Drug screening: Test neuropsychiatric drugs on human-derived neural tissue instead of animal models
2. Neurodegeneration research: Model Alzheimer’s, Parkinson’s, and autism spectrum disorders in controlled environments
3. Personalized medicine: Create patient-specific organoids to test treatment efficacy before clinical trials
4. Neurotoxicology testing: Evaluate environmental toxins on developing brains
5. Brain-computer interface R&D: Test neural signal decoding algorithms on realistic tissue rather than synthetic electrodes

Limitations:

• Not for general-purpose computation (too slow, requires life support)
• Limited lifespan and scalability challenges
• High cost per unit compared to silicon alternatives
• Ethical regulatory hurdles remain significant

Biocomputing is best viewed as a wetware research platform—a biological laboratory that happens to contain neural tissue—rather than an alternative computing substrate. The real revolution may be in the insights gained from studying living neural systems, which could then inform better AI architectures, but the organoids themselves won’t replace our smartphones.

*When will we have pet Organoids?

Gemini Said:
Short answer: Never. Organoids are not primitive animals, nor are they a stepping stone toward lab-grown pets.

An organoid is a millimeter-scale, dish-bound cluster of tissue without a body, sensory organs, or emotional capacity. Expecting a brain organoid to become a household pet confuses isolated biological computing tissue with a complete living organism.

Here is why organoid “pets” are biologically and structurally impossible:

• No Body or Sensory Infrastructure: A pet requires a peripheral nervous system, eyes, ears, vocal cords, limbs, and a metabolic system. Organoids lack a vascular network (blood vessels) to grow beyond a few millimeters; without artificial life support delivering oxygen and nutrients, the core cells suffocate and die.

• Absence of Limbic/Emotional Architecture: The behavior of a pet—greeting you, showing affection, feeling hunger—is driven by complex endocrine systems, hormones (like oxytocin), and an integrated brain structure. Organoids are isolated cell cultures that process electrical pings, not creatures capable of emotional bonding or subjective experience.

• The Sunk-Cost of Living Tissue: Organoids are grown in sterile incubators, kept at exact temperatures, and fed a precise cocktail of growth factors. Exposing a wetware culture to open air or a living room environment would result in rapid bacterial contamination and cell death within hours.

If you want a biological companion that greets you at the door, nature solved that problem millions of years ago with real animals. Biocomputing research exists to replace silicon chips for specific processing tasks and test pharmaceuticals—not to engineer synthetic creatures.

TITLE: New autism therapy shows surprising benefits even in adult mice

URL: https://www.sciencedaily.com/releases/2026/08/260805082508.htm

Blocking the glycine transporter SLC6A20 restored important brain signaling and improved social, communication, and repetitive behaviors in autism-related mouse models. The treatment also worked in human brain organoids and showed lasting effects in adult mice, suggesting the brain may remain more treatable later in life than previously thought.

#stemcells #science

Dr Thomas Hartung is an environmental toxicologist at Johns Hopkins University, in Baltimore, who has spent his career trying to replace animal testing with specialised tissue cultures called organoids
and, more recently, with artificial intelligence.

Last May, he announced his most ambitious endeavour yet
—to create a "Human Exposome Project".

It is ambitious because it aims to do for environmental influences on the body what the "Human Genome Project" did for genetic ones.

But it was badly timed because it came shortly after the election of an American administration that is the most hostile to environmental matters in living memory
